The control apparatus 200 may change achannel of the display apparatus 100, adjust a volume, selectterrestrial broadcasting, cable broadcasting, or satellite broadcasting,or set a configuration.

The display apparatus 100 may be a flat display apparatus, a curveddisplay apparatus having a curved screen, or a flexible displayapparatus that may adjust a curvature. Examples of an output resolutionof the display apparatus 100 may include high definition (HD), full HD,ultra HD, and a resolution higher than ultra HD.

The term ‘user’ used herein refers to a person who controls a functionor an operation of the display apparatus 100 by using the controlapparatus 200 and examples of the user may include a viewer, a manager,and an installer.

The display apparatus 100 may provide a plurality of item areas in orderto display a plurality of item lists corresponding to a plurality ofcategories on a display 115. When the display apparatus 100 provides aplurality of item areas, the display apparatus 100 may provide at leastsome of the plurality of item areas in a closed state and at least someof the plurality of item areas in an open state due to a limited displayspace of the display 115. An item area in a closed state may occupy onlya small portion of the display space and thus may indicate that itemscorresponding to a category are included in this item list but notshown. An item area in an open state may occupy a large portion of thedisplay space of the display 115 and thus items included in an item listcorresponding to a category may be shown.

Also, the display apparatus 100 may display a cursor 300, which respondsto an input of the control apparatus 200, on the display 115.

Referring to FIG. 1A, two item areas 310 and 320 are provided on thedisplay 115. The item area 310 may correspond to a category 1, and atext 312 indicating the category 1 may be displayed on a portion abovethe item area 310 to indicate that the item area 310 corresponds to thecategory 1. Small images 311 showing items of an item list correspondingto the category 1 may be displayed on the item area 310. Each item listmay include one or more item. The item area 310 may be in a closedstate, and an image or images of one or a very small number of items inthe item list corresponding to the category 1 may be displayed on theitem area 310. Hereinafter, an item area in a closed state is referredas a closed item area. A closed item area is mostly used to indicatethat an item list corresponding to a category exists. Items may not bescrolled on a closed item area. Also, items displayed on a closed itemarea may not be selected or may not be activated. However, it will beunderstood by one of ordinary skill in the art that even items displayedon a closed item area may be selected or activated.

Scrolling is an operation, which vertically or horizontally moves atext, an image, or a video across a monitor or a display of a computeror a television. Scrolling does not change a layout of text or an imagebut gradually moves the text or the image in a certain direction on thescreen such that a user can view the text or the image after scrolling.Scrolling is often carried out on a computer by a control processor(CPU) or a graphics card.

The item area 320 may correspond to a category 2, and a text 327indicating the category 2 may be displayed on a portion above the itemarea 320 to indicate that the item area 320 corresponds to the category2. Items of an item list corresponding to the category 2 may bedisplayed on the item area 320. In FIG. 1A, items 321, 322, 323, 324,325, and 326 are displayed on the item area 320. The item area 320 maybe in an open state, and at least some items of the item listcorresponding to the category 2 may be displayed on the item area 320.Hereinafter, an item area in an open state is referred to as an openitem area. Items displayed on an open item area may be selected or maybe activated. Also, the user may scroll the open item area 320 by usingthe control apparatus 200. Also, the user may select one of the items321-326 displayed on the open item area 320 by using the controlapparatus 200, and thus the selected item may be changed to an activestate. Content corresponding to the item in the active state may bedisplayed on a part or whole of the display 115 of the display apparatus100 and the user may use the content corresponding to the item in theactive state.

In general, an item list including a plurality of items may be longerthan an item area. Accordingly, the item list for the open item area 320may be longer than the open item area 320 for displaying items, and thusonly some of the items of the item list may be displayed on the openitem area 320. Accordingly, when the user wants to continuously moveitems of the item list that are not shown on the open item area 320, theuser clicks the cursor 300 on an edge of the open item area 320 to movethe open item area 320 to the edge. The above operation is called edgescrolling. Accordingly, referring to FIG. 1A, the user may furtherperform scrolling on the far left of the open item area 320 by using thecontrol apparatus 200 to display items, which are arranged at the leftof the item 321, on the open item area 320. Also, the user may furtherperform scrolling on the far right of the open item area 320 to displayitems, which are arranged at the right of the item 326, on the open itemarea 320.

A plurality of item areas may be provided to respectively correspond toa plurality of categories. The plurality of categories may be set invarious ways.

One of the categories may include items that are suggested by a serviceprovider (e.g., FEATURED).

One of the categories may include items that are recently activated bythe user (e.g., RECENT).

One of the categories may include, for example, advertisement items.

One of the categories may include items (e.g., preferred channels) thatare preferred by the user.

It will be understood by one of ordinary skill in the art that movieitems, game items, news items, etc. may be set in various ways ascategories.

Each item may indicate content. Examples of an item indicating contentmay include an item indicating image content, such as a movie or adrama, an item indicating audio content, such as music, an itemindicating an application, an item indicating a broadcast channel, andan item indicating history information of content executed by the user.

A plurality of items may be displayed as images. For example, when anitem indicates content of a movie or a drama, the item may be displayedas an image of a movie or drama poster. Also, when an item indicatesaudio content such as music, the item may be displayed as an image of amusic album poster. Also, when an item indicates an application, theitem may be displayed as an image of the application or a screen shot ofthe application. Also, when an item indicates a broadcast channel, theitem may be displayed as an image of a latest screen shot of thebroadcast channel or an image of a program that is being currentlybroadcast. Also, when an item indicates history information of contentthat is executed by the user, the item may be displayed as an image of alatest screen shot of the content.

Also, an item may indicate an interface for connecting the displayapparatus 100 to an external apparatus or may indicate an externalapparatus that is connected to the display apparatus 100. For example,an item indicating an interface for connecting an external apparatus mayindicate a port of an image display apparatus to which the externalapparatus is connected. Examples of an item indicating an externalapparatus may include an item indicating an HD multimedia interface(HDMI) port, an item indicating a component jack, an item indicating aPC port, and an item indicating a universal serial bus (USB) port. Also,an item indicating an external apparatus may indicate the externalapparatus that is connected to an interface.

The cursor 300 is an indicator that is used to show a position on acomputer monitor or a display apparatus, in response to a text input ora pointing device, in a computing apparatus. An indicator that is usedto show a position on a display in response to an input of a pointingdevice, such as a mouse, is generally called a pointer. Referring toFIG. 1A, when the user moves the control apparatus 200, the cursor 300may correspondingly move to a position on the screen of the display 115.

Referring to FIG. 1A, the cursor 300 is displayed on the screen of thedisplay 115 to correspond to a pointing position of the controlapparatus 200.

Also, according to an exemplary embodiment, a speed at which items areslid and moved on a closed item area may not be linear, and may have aspecific curved shape.

FIG. 21A shows a curve that may be used for a speed at which items areslid on a closed item area according to an exemplary embodiment.

The curve of FIG. 21A is a Bézier curve. The curve starts at a startpoint V₀ (0, 0) and arrives at an end point V₃ (1, 1). A slope of thecurve that is obtained by a control point V₁ (0.8, 0.1) and a controlpoint V₂ (0.2, 0.9) may be used as a speed at which items are slid on aclosed item area. Referring to FIG. 21A, the horizontal axis representsan interval in which sliding occurs. The slope of the curve is small ina front part of the interval, is increased in a middle part of theinterval, and is reduced again in a rear part of the interval.

As such, when the slope of the curve that is a Bézier curve is used as asliding speed, items are moved slowly at an early stage of the sliding,are moved quickly at a middle stage, and are moved slowly again at alate stage. Referring to FIG. 21 B, when a position of a left edge of anitem A that slides on a closed item area at a start point of 0 msec ofsliding is 0, the position of the left edge of the item A that slides onthe closed item area at a next point of 300 msec is −10. The position ofthe left edge of the item A that slides on the closed item area at apoint of 600 msec is −50. The position of the left edge of the item Athat slides on the closed item area at a point of 900 msec is −90. Theposition of the left edge of the item A that slides on the closed itemarea at a point of 1200 msec is −100. That is, since items are movedslowly at an early stage and a late stage of sliding and are movedquickly at a middle stage, the user may pleasantly feel as if thesliding occurs due to a force.

According to an exemplary embodiment, the display apparatus 100 mayprovide a user interface (UI) for setting categories corresponding to aplurality of item areas.
